US 10,257,450 B2 · Multi-frame noise reduction method, and terminal

Abstract

A method and a terminal are provided by various embodiments of the present invention in which: M cameras are configured to continuously shoot a same scene for K times, where M≥2, K≥2, and each of the M cameras simultaneously collects one frame of image at each time of shooting; and a processor, connected to the M cameras and configured to perform registration on images obtained at the K times of shooting, and perform temporal and spatial filtering on the registered images. In the embodiments of the present invention. Because the multiple cameras simultaneously collect an image at each time of shooting, a time interval at which a particular quantity of images are collected by the terminal is shorter than that at which the particular quantity of images are collected by a single camera, and a probability of an occurrence of hand trembling or object motion within the time interval also correspondingly decreases.

A multi-frame noise reduction method, comprising:

using M cameras on a terminal to continuously shoot a same scene for K times, wherein M≥2, K≥2, and each of the M cameras simultaneously collects one frame of image at each time of shooting;
for each time of the shooting in the K times:
registering M frames collected by the M cameras;
and
generating a composite frame from the registered M frames based on shift amounts among locations of the M cameras to generate K composite frames;
registering the K composite frames;
and
performing temporal and spatial filtering on the registered composite K frames.
